Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed June 9,1904- Serial No. 211.806.

To all whom it may concern:

Be it known that I, OHARLEY BIoLY, a citi- Zen of the United States, residing at Pound, in the county of Marinette and State of Wisconsin, have invented new and useful Improvements in Steam-Boilers, of which the following is a specification.

This invention relates to a steam-boiler for generating steam with great rapidity on a minimum consumption of coal, for quickly drying the steam generated, and for an arrangement and disposition of parts whereby the entire boiler may be easily and quickly cleaned from any deposit of ashes, soot, and fine coal in the fire-tubes and heating-chambers through which the products of combustion have passed on their way to the atmosphere.

In the accompanying drawings, Figure 1 represents a vertical longitudinal sectional view through a horizontal or locomotive boiler. Fig. 2 is a vertical sectional view of an upright.

Similar letters refer to the same parts on both figures.

Directing attention first to Fig. 1, the boiler-shell is indicated by A, the fire-box by B, and the stack or outlet-flue by O. Within the boiler-shell, near its front head a, is a heating-chamber or header D, suitably fixed in place and provided with a cleaning-door E, opening through the front a into the sparkchamber F, from the upper side of which the flue or stack O projects. A similar heatingchamber or header G is fixed within the boiler and near the rear thereof above the fire-box. It is closed by a door H, opening through the rear head 5 of the boiler. Between the top of the fire-box B and the lower part of the header D a series or tier of fire-tubes I extends,through which tubes the heated products of combustion pass into the header on their way to the stack. A second series or tier of fire-tubes J connects the top of the header D with the bottom of the header Gr, which latter is adapted for communication with the fire-box through the medium of a pipe L, which may be normally closed by a suitable valve, (not shown,) while a third tier or series of firetubes K extends from the top of the header G to and through the front head a. Each tier of fire-tubes has an upward inclination v in the direction of movement of the products of combustion, thereby facilitating the draft of the furnace, increasing the temperature of the burning gases, and generating a greater quantity of steam in the boiler. The headers D and G are highly heated by the passage therethrough of all the burning gases, and as they present a large superficial area they assist materially in the generation of steam. The flues of tier K and the top of the header G are here shown in the steam-space of the boiler, an arrangement by which steam is rapidly dried in large quantities ready for use in the arts.

In Fig. 2 I have shown a vertical boiler with ashellA, afire-boX B, and a smoke-flue O, leading from a smoke-chamber F. In this instance the fire-box B rises higher at the front of the boiler than at the rear thereof. From this upwardly-projecting portion 6 flues I pass with an upward inclination to the bottom of the vertically-placed header or heating-chamber D, which latter is adapted for communication with the fire-box B and smoke-chamber F, respectively, through the medium of pipes D D which may be normally closed by suitable valves. (Not shown.) The headers D G and smoke-chamber F are connected by tiers of flues J and K in substantially the same manner as that represented in Fig. 1. The height of the headers D and G is such that it has been found advantageous to apply two doors E and E, through which the firetubes I and J may be cleaned, while the header G, which is adapted to communicate with the fire-box through the medium of a pipe L, is also supplied with two doors H H, it being understood that the pipe L may be normally closed by a suitable valve. (Not shown.)

Having thus fully described the invention, what is claimed as new is In an engine-boiler, a combustion-chamber arranged at one end of the boiler and asmokechamber at the other end thereof, a header arranged in the boiler adjacent to and adapted for communication with the smoke-chamber, a second header disposed in the boiler above the combustion-chamber, tubes connecting the combustion-chamber with the firstnamed header and the second header with the smoke chamber, and tubes connecting the In testimony whereof I affix my signature in headers one with the other, all of the tubes presence of two witnesses. being upwardly inclined in the direction of travel of the products of combustion and the second header and tubes extending between the latter and smoke-chamber being disposed Within the steam-space.
